When electronic devices receive strong electromagnetic waves, unwanted electric currents can be induced in the circuit, interfering with intended operations. EMI filters deliver superior EMI ...
A snubber circuit limits voltage spikes in power converters. Snubbers are also used in the output of Class-D audio amplifiers for the same reasons (Fig. 1). When the transistor you use to switch the ...
Power-supply designers struggle to reduce the ill effects of the reverse-recovery charge in switching diodes, especially in high-voltage circuits. The recovery mechanism causes unwanted ringing and ...
